Long-Term Retention of Diverse Paleontologists Requires Increasing Accessibility

Autor: Aja Mia Carter, Erynn H. Johnson, Elena R. Schroeter

Publikováno v: Frontiers in Ecology and Evolution, Vol 10 (2022)

Geoscience encompasses a variety of scientific subdisciplines aimed at exploring, understanding, and predicting global phenomena. Yet despite its global reach, the geosciences are the least diverse of the STEM disciplines. Paleontology, a subdiscipli

Soft-Tissue, Rare Earth Element, and Molecular Analyses of Dreadnoughtus schrani, an Exceptionally Complete Titanosaur from Argentina

Autor: Elena R. Schroeter, Paul V. Ullmann, Kyle Macauley, Richard D. Ash, Wenxia Zheng, Mary H. Schweitzer, Kenneth J. Lacovara

Publikováno v: Biology, Vol 11, Iss 8, p 1158 (2022)

Evidence that organic material preserves in deep time (>1 Ma) has been reported using a wide variety of analytical techniques. However, the comprehensive geochemical data that could aid in building robust hypotheses for how soft-tissues persist over

Soft Tissue and Biomolecular Preservation in Vertebrate Fossils from Glauconitic, Shallow Marine Sediments of the Hornerstown Formation, Edelman Fossil Park, New Jersey

Autor: Kristyn K. Voegele, Zachary M. Boles, Paul V. Ullmann, Elena R. Schroeter, Wenxia Zheng, Kenneth J. Lacovara

Publikováno v: Biology, Vol 11, Iss 8, p 1161 (2022)

Endogenous biomolecules and soft tissues are known to persist in the fossil record. To date, these discoveries derive from a limited number of preservational environments, (e.g., fluvial channels and floodplains), and fossils from less common deposit

Proteomic method to extract, concentrate, digest and enrich peptides from fossils with coloured (humic) substances for mass spectrometry analyses

Autor: Elena R. Schroeter, Kevin Blackburn, Michael B. Goshe, Mary H. Schweitzer

Publikováno v: Royal Society Open Science, Vol 6, Iss 8 (2019)

Humic substances are breakdown products of decaying organic matter that co-extract with proteins from fossils. These substances are difficult to separate from proteins in solution and interfere with analyses of fossil proteomes. We introduce a method

Bone protein 'extractomics': comparing the efficiency of bone protein extractions of Gallus gallus in tandem mass spectrometry, with an eye towards paleoproteomics

Autor: Elena R. Schroeter, Caroline J. DeHart, Mary H. Schweitzer, Paul M. Thomas, Neil L. Kelleher

Publikováno v: PeerJ, Vol 4, p e2603 (2016)

Proteomic studies of bone require specialized extraction protocols to demineralize and solubilize proteins from within the bone matrix. Although various protocols exist for bone protein recovery, little is known about how discrete steps in each proto

Molecular tests support the viability of rare earth elements as proxies for fossil biomolecule preservation

Autor: Kristyn K. Voegele, David E. Grandstaff, Mary Higby Schweitzer, Elena R. Schroeter, Wenxia Zheng, Richard D. Ash, Kenneth J. Lacovara, Paul V. Ullmann

Publikováno v: Scientific Reports, Vol 10, Iss 1, Pp 1-11 (2020)
Scientific Reports

The rare earth element (REE) composition of a fossil bone reflects its chemical alteration during diagenesis. Consequently, fossils presenting low REE concentrations and/or REE profiles indicative of simple diffusion, signifying minimal alteration, h

The molecular evolution of feathers with direct evidence from fossils

Autor: Elena R. Schroeter, Yanhong Pan, Feixiang Wu, Liang Hu, Zhiheng Li, Xiaoting Zheng, Min Wang, Tao Zhao, Mary Higby Schweitzer, Xing Xu, Wenxia Zheng, Roger H. Sawyer, Jingmai K. O’Connor, Xiaoli Wang, Michael W. Pennington, Zhonghe Zhou

Publikováno v: Proceedings of the National Academy of Sciences. 116:3018-3023

Dinosaur fossils possessing integumentary appendages of various morphologies, interpreted as feathers, have greatly enhanced our understanding of the evolutionary link between birds and dinosaurs, as well as the origins of feathers and avian flight.
